摘要:
A polymer composition comprising a density equal to or greater than about 0.947 g/cc, a high load melt index from about 1 g/10 min to about 30 g/10 min, and a tensile natural draw ratio less than about 14167 ρ-12958, where ρ is the density (g/cc) of the composition. A polymer composition comprising a tensile natural draw ratio less than about 14167ρ-12958, where ρ is the density (g/cc) of the composition and wherein less than about 1 weight percent of the composition comprises non-polymeric additives.
